--- Comment #1 from Nicolai Hähnle nhaehnle@gmail.com --- Could you please provide a log when running the game with environment variable R600_DEBUG=vs,tcs,tes,gs,ps,cs?

Also, could you please run with a debugger and debug symbols installed, and provide a backtrace? Thank you!

As discussed on IRC, the error goes away when dumping shaders, which means that the bug might be related to multi-threading. This suggests the attached patch.

Did you get around to testing with the provided patch? That would still be useful, though please use the newly attached instead if you do. Thanks!

--- Comment #9 from Christian Lanig freedesktop@lanig.email --- Thanks a lot for your help!

I am still trying to give you the requested info as soon as possible but I ran into several issues trying to compile Mesa and I am also a bit busy sometimes. However, I know how to fix the remaining issues and it will just be a matter of time to fix the whole string to the end. It's also pretty educational.

But I would also be happy when someone who owns this game and compiles Mesa regularly could test this patch on his own to accelerate the procedure.

The only thing I could find out so far was that it also crashes with 17.0.3 which is the standard version of Ubuntu 17.04 and it also runs fine while the shaders are dumped.

--- Comment #10 from Christian Lanig freedesktop@lanig.email --- Sorry that it took so long.

I have been able to compile Mesa from git and noticed that the patch has already been applied. Unfortunately Hero Siege still doesn't run without dumping both vertex and pixel shaders.
